Depending on your version of software, the i1Pro spectrophotometer (i1) can contain licenses for creating profiles in i1Profiler software or you may use it simply as a measurement device within your i1Profiler software.

The i1, when connected should act as a dongle but if i1Profiler software launches in DEMO mode only (with no green checkmarks), this might indicate, that i1Profiler does not recognize your i1.

If you want to do measurements with your connected i1 but i1Profiler shows a message 'Device not connected' in the measurement windows, this might also indicate, that i1Profiler does not recognize your i1.
